Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, concrete structure of the present invention, principle and behaviour are described in further detail.
The present invention proposes a kind of lucite seal operation case for glass chemistry polishing, structure as shown in Figure 1, 2, 3.As shown in Figure 1, this kind of seal operation case and bag contain front vertical plate 1, right vertically side plate 2, left vertically side plate 3, rear vertical plate 4, base plate 5, top board 6.
If the top board 6 in Fig. 1 is main detection form.
As in Fig. 1, front vertical plate 1 contains left hand socket 11, right hand socket 12, operation chamber door 13 and control box door closure 14.Left hand socket 11 and right hand socket 12 are made up of the gloves 112 in Fig. 3, gloves hoop 111, gloves circle 113 simultaneously, the upset of the edge of gloves 112 is fixed in the groove of gloves circle 113 by gloves hoop 111, carry out lock sealing through gloves hoop 111, and gloves circle 113 bonds to front vertical plate 1 by chloroform.The embedding female reinforcement patches 17 of band on operation chamber door 13 in bonding Fig. 2, to increase sealing and the intensity of operation chamber door 13.Operation chamber door 13 is furnished with the control box door closure 14 being with external screw thread 15 and sealing ring 16 as shown in Figure 3, increases the sealing of operation chamber door 13.Internal thread in the external screw thread of control box door closure 14 and reinforcement patches 17 jointly locks and operates chamber door 13.
As shown in Figure 1, there are air inlet/aqueous slkali hand-hole 21, case external admission tank 22, air inlet tank aqueous slkali discharge orifice 27 and right handle 28 in the outside of right vertically side plate 2; There is air inlet tank 24 in case the inner side of right vertically side plate 2.Upper surface air inlet/aqueous slkali the hand-hole 21 of case external admission tank 22.Case external admission tank 22 is equal with the height of air inlet tank 24 in case, but volume is respectively 200mm × 30mm × 20mm, 200mm × 175mm × 50mm, is to be connected by air inlet bottom of gullet square orifice 23.When in the case that the differential pressure of atmospheric pressure in extraneous air and control box is greater than when case external admission tank 22 aqueous slkali all flows to air inlet tank 24 in case during air inlet tank 24 aqueous slkali height pressure difference, then gas flows in case from outside by air inlet 25 in air inlet tank 24 in air inlet tank 24, air inlet bottom of gullet square orifice 23, case in air inlet/aqueous slkali hand-hole 21, case and case, and gas have passed through the filtration of tank aqueous slkali simultaneously; Anti-then when the differential pressure of atmospheric pressure in extraneous air and control box is less than air inlet tank 24 aqueous slkali height pressure difference in case that case external admission tank 22 aqueous slkali all flows in case after air inlet tank 24, in case, air inlet tank realizes isolation to internal gas and purified treatment.Baffle plate 26, in order to prevent intake velocity too fast, evokes aqueous slkali and splashes and the experiment that has influence in case.Air inlet tank aqueous slkali discharge orifice 27 is used for discharging aqueous slkali in air inlet tank.
As depicted in figs. 1 and 2, there is in case tank 32 of bleeding the inner side of left vertically side plate 3; There are to bleed outside case tank 34 and left handle 38 in the outside of left vertically side plate 3; Tank 34 of bleeding outside case comprises tank aqueous slkali hand-hole 35 of bleeding, bleed tank aqueous slkali discharge orifice 36, outside bleeding point 37, bleed outside case in tank 34 and employ dividing plate 341, blow vent 342 is left in the front end of dividing plate 341, division separates spatial transition 343, and inside aqueous slkali when preventing the speed of evacuation too fast is splashed to outside bleeding point 37.Bleed in the case upper surface of tank 32 is gas outlet 31 in case.To bleed in tank 34 and the case height of tank 32 of bleeding outside case is equal, and volume is respectively 200mm × 175mm × 40mm, 200mm × 30mm × 20mm, is to be connected by bottom of gullet square orifice 33 of bleeding.When the aqueous slkali that the air pressure in case and spatial transition pressure reduction are greater than in case tank 32 of bleeding all flow to bleed tank 34 outside case time case outside bleed the solution height pressure reduction of tank 34 time, then in control box, bleed in gas outlet in case 31, case to bleed tank 32, bleed bottom of gullet square orifice 33, case tank 34, tank aqueous slkali hand-hole 35 of bleeding, tank aqueous slkali discharge orifice 36 of bleeding, outside bleeding point 37 of gas flows to outside case, gas have passed through the filtration of tank aqueous slkali simultaneously, realizes purified treatment; Otherwise, when the aqueous slkali that the air pressure in case and spatial transition pressure reduction are less than in case tank 32 of bleeding all flow to bleed tank 34 outside case time case outside bleed the solution height pressure reduction of tank 34 time, tank of bleeding in case realizes isolation to internal gas and purified treatment.Bleed tank aqueous slkali hand-hole 35 and tank aqueous slkali discharge orifice 36 of bleeding realizes injection and the discharge of aqueous slkali respectively.
This is used for the concrete use step of the lucite seal operation case of glass chemistry polishing: outside bleeding point is connected air-extractor, air inlet tank aqueous slkali discharge orifice, tank aqueous slkali discharge orifice of bleeding all connects machinery valve with tank aqueous slkali hand-hole of bleeding, then to case external admission tank, air inlet tank in case, the tank of bleeding outside tank and case of bleeding in case injects aqueous slkali, need than air inlet bottom of gullet square orifice and the bottom of gullet square orifice height height 10mm that bleeds, tank internal solution is no more than 50mm, this can suitably can suitably adjust with the intensity of bleeding of air-extractor.Then experiment article are put in control box by operation chamber door, then tighten seal operation chamber door lid to seal, observed by top board, just experimental implementation can be started, in experimentation, air-extractor is forbidden opening, and after experiment completes, just can open air-extractor carry out taking a breath and purified treatment, according to the speed of evacuation of the equipment of bleeding, wait for the appropriate time, the glass after polishing can be taken out by open operation chamber door.
